TANK-GARx To all whom'it may concern:

Beit known that I, TnoMAs R. BROWN, a

citizen of the United States, residin in the city, county, and State ofNew Yor have invented a certainnew and useful Improve'- ment inTank-Cars, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which I itappertains to make and use the same, reference being had to theaccompanying drawings', forming part of this specification, in

Figure 1 is a side elevational 'view of tank car constructed inaccordance with my in# vention; Fig. 2 'is a plan view illustratingone-half` of the unjderframing; Fig. 3 is a sectional view taken on, theline 3 3 of Fig. 1

'- Fig. 4 is a sectional view takenon the line trates a' modified formvof connection between the tank and body bolster.

This invention relates to a new and useful improvement in 'tank cars,one of the objects being to .provide a car in which the tank is end toend of thc'car and serve as draft mem-4 free to expand or contractlongitudinally. Ina construction of this character the rivets thatsecure the different sections of the tank together will notA be exposedto a shearinT strain when the tank and underframe tend to independentlyexpand or contract.

Another object is to provide a tank. that can be .supported by a lightandsimple underframe.

Another object is to provide means wherebythe tank may. be easilyremoved from the underfranie.

With theseobjects in view, theinvention consists in the construction,Iarrangement and combination of the several parts, all as will behereinafter described and* afterward pointed out in the claims,

A.Referring to the accom anying drawings, 1 indicates the longitu inalsills, herein shown as channels reinforced by angles at their loweredges and provided with a cover plate 2. These sills preferably extendfrom hers.

gitudinal sills, said blocks being with. a pair Iof inwardly p'rojectinanges 4 which are riveted to the sills and w ose inner ends serve asdraft lugs. A draft rigging1 er interposed between the lugs 4 and ano'tpair of lugs 6. I have herein shown the ordinary spring draft riggingwhich consists of a spring arranged between two follower plates, thefollowers abutting the lugs 4 and 6; However, the use of my invention isnot limited to any particular kind of draft gear.

The tank consists of a middle cylindrical section 7, end sections 8,intermediate sec..` tions 9, headsland the usual filling-dome.;- Theends of the intermediate sectional-1f A. have telescopic engagement withthe middlej' and end sections, that is, they are arranged inside ofandriveted to said sections.

f The flanges 16 rest ontop of the longitudinal sills and aile securedthereto by means of bolts 18. It will be noticed in this c onnecu tionthat while this tank supporti is ri "diy secured-to both the tank ansills the weight of the tank does not place a shearing strain on thesecuring means.

` If `desired1 the above-mentioned supportmaybe coFmposed of two Z-barsarranged as ig. 7 r

Body. bolsters 21 are locatedunder' the end 2Cv plate could be employed.

my invention, side 5 as channels are secured to tbe under side ol theend sections 8, above the body bolsters.

Yertically arranged connection plates 2.3

are secured at their upper ends to the meinbers 22 by means of bolts 24.The lower ro edges of said plates rest on tbe body bolstors and aresecured thereto by means o'l'bolts These plates are preferably arranged.1in pairs and .located between tbe longitudinal sills and the ends oftheA body bolsters, show-n- I5 in the drawings.

However, it will be understood that this construction could be varied inmanyavayslor example, tbe plates could' A extend from. ond to end ol tbebolsters, or, instead of being arranged in pairs a single The plates areol suficient strength to support tbe tank and are devoid of' stiileningmembers, the object 'being to forni a connection between tbc tank andunderfraine of sullicient flexibility to '25 permit tbe tank to' expandor contract longitudinally, independently of tbe underlranie andwitlunit straining tbc rivets which. secure tbe tank sections together.The connection thus made is practically a hinge.

30' Instead of having a rigid connection at tbe center and flexibleconnections at tbe bolster points, the rigid connection could be at onebolster, and the other connection or connections flexible. l

' In tbe modified form shown in Fig. 8, the body bolster 21 and the tanksaddle 22 are provided with suitable reci-isses to receive tbeapproximately semi-circular ends of'a rigid member 2. This rigid memberis pivot- 40 ally connected to the tank saddle and bolster 'by means of'pins 24 and 25?-, respectively, and performs the same function as tbcilexible plates 23.

Ina car constructed in accordance with and. end sills are unnecessary.

The tank can. be detacbed from tbe underfranie by simply removing tbebolts ll and 24.
